"How strange this is! what can be the meaning of it! But the whole of their behaviour to each other has been unaccountable! How cold, how composed were their last adieus! How languid their conversation the last evening of their being together! In Edward's farewell there was no distinction between Elinor and me: it was the good wishes of an affectionate brother to both. Twice did I leave them purposely together in the course of the last morning, and each time did he most unaccountably follow me out of the room. And Elinor, in quitting Norland and Edward, cried not as I did. Even now her self-command is invariable. When is she dejected or melancholy? When does she try to avoid society, or appear restless and dissatisfied in it?"
Chapter 11:
Elinor could not be surprised at their attachment. She only wished that it were less openly shewn; and once or twice did venture to suggest the propriety of some self-command to Marianne. But Marianne abhorred all concealment where no real disgrace could attend unreserve; and to aim at the restraint of sentiments which were not in themselves illaudable, appeared to her not merely an unnecessary effort, but a disgraceful subjection of reason to common-place and mistaken notions. Willoughby thought the same; and their behaviour at all times, was an illustration of their opinions.
Chapter 19:
Elinor sat down to her drawing-table as soon as he was out of the house, busily employed herself the whole day, neither sought nor avoided the mention of his name, appeared to interest herself almost as much as ever in the general concerns of the family, and if, by this conduct, she did not lessen her own grief, it was at least prevented from unnecessary increase, and her mother and sisters were spared much solicitude on her account.
Such behaviour as this, so exactly the reverse of her own, appeared no more meritorious to Marianne, than her own had seemed faulty to her. The business of self-command she settled very easily;—with strong affections it was impossible, with calm ones it could have no merit. That her sister's affections WERE calm, she dared not deny, though she blushed to acknowledge it; and of the strength of her own, she gave a very striking proof, by still loving and respecting that sister, in spite of this mortifying conviction.
Chapter 22:
"It is strange," replied Elinor, in a most painful perplexity, "that I should never have heard him even mention your name."
"No; considering our situation, it was not strange. Our first care has been to keep the matter secret.— You knew nothing of me, or my family, and, therefore, there could be no OCCASION for ever mentioning my name to you; and, as he was always particularly afraid of his sister's suspecting any thing, THAT was reason enough for his not mentioning it."
She was silent.—Elinor's security sunk; but her self-command did not sink with it.
"Four years you have been engaged," said she with a firm voice.
Chapter 23:
The necessity of concealing from her mother and Marianne, what had been entrusted in confidence to herself, though it obliged her to unceasing exertion, was no aggravation of Elinor's distress. On the contrary it was a relief to her, to be spared the communication of what would give such affliction to them, and to be saved likewise from hearing that condemnation of Edward, which would probably flow from the excess of their partial affection for herself, and which was more than she felt equal to support.
From their counsel, or their conversation, she knew she could receive no assistance, their tenderness and sorrow must add to her distress, while her self-command would neither receive encouragement from their example nor from their praise. She was stronger alone, and her own good sense so well supported her, that her firmness was as unshaken, her appearance of cheerfulness as invariable, as with regrets so poignant and so fresh, it was possible for them to be.
Chapter 32:
Elinor only was sorry to see them. Their presence always gave her pain, and she hardly knew how to make a very gracious return to the overpowering delight of Lucy in finding her STILL in town.
"I should have been quite disappointed if I had not found you here STILL," said she repeatedly, with a strong emphasis on the word. "But I always thought I SHOULD. I was almost sure you would not leave London yet awhile; though you TOLD me, you know, at Barton, that you should not stay above a MONTH. But I thought, at the time, that you would most likely change your mind when it came to the point. It would have been such a great pity to have went away before your brother and sister came. And now to be sure you will be in no hurry to be gone. I am amazingly glad you did not keep to YOUR WORD."
Elinor perfectly understood her, and was forced to use all her self-command to make it appear that she did NOT.
Chapter 37:
She was very far from wishing to dwell on her own feelings, or to represent herself as suffering much, any otherwise than as the self-command she had practised since her first knowledge of Edward's engagement, might suggest a hint of what was practicable to Marianne. Her narration was clear and simple; and though it could not be given without emotion, it was not accompanied by violent agitation, nor impetuous grief.—THAT belonged rather to the hearer, for Marianne listened with horror, and cried excessively. Elinor was to be the comforter of others in her own distresses, no less than in theirs; and all the comfort that could be given by assurances of her own composure of mind, and a very earnest vindication of Edward from every charge but of imprudence, was readily offered.
Chapter 37:
"Yes. But I did not love only him;—and while the comfort of others was dear to me, I was glad to spare them from knowing how much I felt. Now, I can think and speak of it with little emotion. I would not have you suffer on my account; for I assure you I no longer suffer materially myself. I have many things to support me. I am not conscious of having provoked the disappointment by any imprudence of my own, I have borne it as much as possible without spreading it farther. I acquit Edward of essential misconduct. I wish him very happy; and I am so sure of his always doing his duty, that though now he may harbour some regret, in the end he must become so. Lucy does not want sense, and that is the foundation on which every thing good may be built.—And after all, Marianne, after all that is bewitching in the idea of a single and constant attachment, and all that can be said of one's happiness depending entirely on any particular person, it is not meant—it is not fit—it is not possible that it should be so.— Edward will marry Lucy; he will marry a woman superior in person and understanding to half her sex; and time and habit will teach him to forget that he ever thought another superior to HER."—
"If such is your way of thinking," said Marianne, "if the loss of what is most valued is so easily to be made up by something else, your resolution, your self-command, are, perhaps, a little less to be wondered at.—They are brought more within my comprehension."
"I understand you.—You do not suppose that I have ever felt much.—For four months, Marianne, I have had all this hanging on my mind, without being at liberty to speak of it to a single creature; knowing that it would make you and my mother most unhappy whenever it were explained to you, yet unable to prepare you for it in the least.— It was told me,—it was in a manner forced on me by the very person herself, whose prior engagement ruined all my prospects; and told me, as I thought, with triumph.— This person's suspicions, therefore, I have had to oppose, by endeavouring to appear indifferent where I have been most deeply interested;—and it has not been only once;—I have had her hopes and exultation to listen to again and again.— I have known myself to be divided from Edward for ever, without hearing one circumstance that could make me less desire the connection.—Nothing has proved him unworthy; nor has anything declared him indifferent to me.— I have had to contend against the unkindness of his sister, and the insolence of his mother; and have suffered the punishment of an attachment, without enjoying its advantages.— And all this has been going on at a time, when, as you know too well, it has not been my only unhappiness.— If you can think me capable of ever feeling—surely you may suppose that I have suffered NOW. The composure of mind with which I have brought myself at present to consider the matter, the consolation that I have been willing to admit, have been the effect of constant and painful exertion;—they did not spring up of themselves;—they did not occur to relieve my spirits at first.— No, Marianne.—THEN, if I had not been bound to silence, perhaps nothing could have kept me entirely—not even what I owed to my dearest friends—from openly shewing that I was VERY unhappy."—
'Self-command' is used once in Persuasion, once in Pride and Prejudice, three times in Mansfield Park, five times in Emma, and not at all in Northanger Abbey. It is notable that of the eight times it occurs in S&S it is only attributed to Elinor, and it is put center stage in Chapter 37, where it is used twice, and discussed specifically between the characters, rather than simply being a passing comment.
